Treat 12 as 12/1 that means 12 divided into 1 part
1/4 times 12/1
multiply the top and the bottom becuase
![\frac{x}{y}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7By%7D%20)
times
![\frac{z}{t}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bz%7D%7Bt%7D%20)
=
![\frac{x times z}{y times t}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%20times%20z%7D%7By%20times%20t%7D%20)
so
1/4 times 12/1=(1 times 12)/(4 times 1)=12/4=3/1=3
the answe ris 3
D. if something is directly proportional then if something happens to X the exact same thing needs to happen to Y
Pretty Sure it’s y=x+(-.8) haven’t done algebra in a bit. Sorry if wrong. :/
Answer:
m = 0
Step-by-step explanation:
Slope Formula: ![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Simply plug in the coordinates into the formula:
m = (-3 + 3)/(4 - 6)
m = 0/-2
m = 0
Answer:
The correct option is;
B
Step-by-step explanation:
The given system of inequalities are;
5·x - 4·y > 4...(1)
x + y < 2...(2)
Representing both inequalities as a function of "y", gives;
For, 5·x - 4·y > 4...(1), we have;
-4·y > 4 - 5·x
y < 4/(-4) - 5·x/(-4)
∴ y < 5·x/4 - 1
For x + y < 2...(2), we have;
y < 2 - x
Therefore, y is less than the values given by the equation of the straight line equalities, and the feasible region is given by the common region under both dashed lines representing both inequalities as shown in the attached diagram created using Microsoft Excel
The correct option is therefore, B.
